  1. Mean values were pooled across the 12 week period following insecticide treatment.
  2. Values followed by identical letters do not differ significantly for comparisons between treatments within each column (Tukey test, P > 0.05).
  3. Dry season treatment effect, MANOVA, Pillai's trace 0.3705, F8, 88 = 2.501, P = 0.017.
  4. Wet season treatment effect, MANOVA, Pillai's trace 0.52934, F8, 88 = 3.959, P < 0.001.
